Keyword Density Checker — SEO Optimization

Keyword density refers to the number of times a keyword appears in a text relative to the total word count, expressed as a percentage. It is one of many on-page SEO factors that search engines consider when ranking content.

Ideal Keyword Density

While there is no fixed "magic number," most SEO experts recommend a keyword density of 1% to 3% for your primary keyword. Going above 4-5% risks keyword stuffing penalties from Google, which can actively harm your rankings.

How to Use This Tool

• Paste your full article or page content into the text area.
• Set the minimum word length to filter out very short words.
• Enable "Exclude Stop Words" to filter out common words like "the", "and", "is" that have no SEO value.
• Click Analyze to see a ranked table of all words with their occurrence count and percentage.
• Check that your target keyword appears at a healthy 1-3% density.
